We have experienced a case of comparatively rare anteromedial meniscofemoral ligament (AMMFL) in which the anterior horn of the medial meniscus was attached to the posterolateral wall of the femoral intercondylar fossa. AMMFL was diagnosed and confirmed during therapeutic arthroscopy. The report suggests the need for increased awareness of the possible presence of this. Additionally, we illustrate the anomaly, discuss its controversial clinical significance and review the literature.

Purpose: The authors introduce a new technique of arthroscopic all inside repair using anterolateral and anteromedial portals for lateral meniscus root complete radial tear in patients who underwent concurrent anterior cruciate ligament (ACL) reconstruction. Operative technique: Arthroscope is placed through anteromedial portal and suture hook ($Linvatec^{TM}$, Largo, Florida, USA) is delivered through anterolateral portal. By rotating the suture hook, it penetrates posterior horn of the torn meniscus from femoral to tibial surface for vertical orientation. PDS No. 1 ($Ethicon^{TM}$, Somerville, NJ, USA) is delivered through the suture hook, and then it is withdrawn. Both end of PDS No. 1 are taken out through the anterolateral portal. MAXON 2-0 ($Syneture^{TM}$, Norwalk, Connecticut, USA) is used to penetrates remnant of tibial attachment of the torn meniscus from tibial to femoral surface in a same manner. MAXON 2-0 is changed for PDS No. 1 from tibial to femoral surface by shuttle relay technique. PDS No. 1 is tied using SMC (Samsung Medical Center) knot. Conclusion: All inside repair is a useful technique to achieve anatomical repair and to restore the hoop tension in lateral meniscus root complete radial tear.

This article is to report a new technique for reconstruction of the anteromedial and posterolateral bundles of anterior cruciate ligament by separate tensioning and fixation of the each bundle. Method : Tibial and femoral tunnels were made with conventional technique of anterior cruciate ligament reconstruction. Tibial tunnel was enlarged $5\~7$ mm in anterior-posterior direction to make oval it in cross section. When preparing the Achilles tendon allograft, bone plug portion was trimmed as the conventional technique. The tendinous portion was trimmed as two separate bundles by dividing the tendinous portion longitudinally, so the graft is shaped like 'Y'. The bone plug portion of allograft was inserted into the femoral tunnel and fixed with absorbable cross pins. Two ligamentous portionss of the distal part of the grafts were tensioned separately at the external orifice. Anteromedial bundle was fastened under maximum tension with the knee flexed 90 degrees by post-tie method. The posterolateral bundle was fixed by the same technique with the knee in full extension. Then, an absorbable interference screw was inserted between the two bundles upto the upper end of the tibial tunnel, to get more initial rigidity of the reconstructed graft as well as to locate the two bundles in more anatomic position.

Purpose: This article describes a double-bundle ACL reconstruction technique using a five-strand hamstring tendon autograft with conventional anteromedial bundle reconstruction and additional posterolateral bundle reconstruction. Operative technique: For the tibial tunnel, the conventional single tunnel technique is performed and for the femoral tunnel, the double tunnel technique is performed with the anteromedial and posterolateral bundle. After minimal notchplasty, the anteromedial femoral tunnel is prepared with leaving one milimeter of posterior femoral cortex within the over-the-top, which if positioned at the 11-o'clock orientation for the right knee or at the 1-o'clock position for the left knee. The posterolateral femoral tunnel that is located 5 to 7 mm superior to the inner margin of the lateral meniscus anterior horn at $90^{\circ}$ of flexion is prepared with tile outside-in technique using a 4.5 cannulated reamer. The graft material for the double bundle reconstruction is made of the conventional four-strand hamstring autograft in the anteromedial bundle and of a single-strand semitendinosus tendon in the posterolateral bundle. The anteromedial bundle is fixed with using a rigid fix system on the femoral side and the posterolateral bundle is fixed to tie with the miniplate from the outside femur. Then, with the knee in $10^{\circ}\;to\;20^{\circ}$ of flexion, a bioabsorbable screw is simultaneously applied to achieve tibial fixation with tensioning of both bundles. Conclusion: A double bundle reconstruction with five-strand hamstring autograft, which is designed with a favorable conventional anteromedial bundle and an additional posterolateral bundle to restore rotation stability, seems to be a very effective method for the treatment for ACL instabilities.
